Title: Sealing arrangement between an outboard propulsion unit and the hull of a boat
Inventor: ASO KINICHI
IPC: B63H20/04
Filed: 1981-11-30
Abstract: The invention relates to a sealing arrangement between an outboard propulsion unit and the hull of a boat, the outboard propulsion unit being attached to a motor and being secured on a mounting bed on the hull and projecting down through an opening formed in the hull. To seal off a space between hull and propulsion unit, a sealing diaphragm is fastened to the hull and the propulsion unit. An annular sealing flange arranged above the sealing diaphragm projects from the mounting bed towards the propulsion unit, and an annular seal is provided between the propulsion unit and the sealing flange for sealing off a space lying in between, both ends of the annular seal being fastened to the propulsion unit and to the sealing flange. A water sensor attached to an early warning device is arranged in a space between the sealing diaphragm and the annular seal.
Patent DE-3203736-A1 (DE)
Title: Firedoor
Inventor: MITGUTSCH ALFRED DIPL ING
IPC: E06B5/16
Filed: 1982-02-04
Abstract: What is described is a firedoor, having a reinforcing frame (1-4) formed from metal sections, for example U-sections, and having an outer sheet-metal casing (5) arranged at a distance from the reinforcing frame. The sheet-metal casing (5) contains inlays of heat-insulating material (mineral-fibre mat 16 and fibre plasterboards 17, 18). The lock case (6) of the firedoor is arranged between the reinforcing frame (1-4) and the sheet-metal casing (5). The lock case (6) is fastened so as to bear only on the sheet-metal casing (5), but not on the reinforcing frame (1-4) or its vertical section (1). There is a free play of the lock case (6) relative to the reinforcing frame (1-4) which, if necessary, can be strengthened by a middle horizontal strut (7-9). Preferably, the lock case (6) engages with a pin (20) projecting from its rear side into a bore of the reinforcing frame (1-4), the pin (20) being arranged loosely in the bore. Whilst a high rigidity is ensured in the region of the lock, nevertheless a flexibility, advantageous in the event of a fire, is achieved in respect of thermal expansions which cannot press the door out of the lock. <IMAGE>

Title: Apparatus for assembling and dismantling machine parts of large dimensions and a hydraulic control system for this purpose
Inventor: KHIRWADKAR PRABHAKAR R DR
IPC: B66C23/42
Filed: 1982-07-31
Abstract: The apparatus for assembling and dismantling machine parts of large dimensions consists of a vehicle with a low-bed platform, into the receiving area of which two hydraulically pivotable lifting arms, arranged in parallel next to one another with regard to the longitudinal axis of the vehicle, can be at least partly swung, at the top free and pivotable end of which in each case a load-carrying head is arranged. The main arm is pivotably driven by a piston-cylinder unit supported relative to the deep-bed vehicle, and the secondary arm is pivotably driven by a piston-cylinder unit supported on the main arm, the two piston-cylinder units of a vehicle side being connected in series. It is thereby possible for the load-carrying head to move approximately along a vertical straight line.

Title: Radio system
Inventor: MUELLER FRIEDRICH
IPC: B61L3/12
Filed: 1982-08-25
Abstract: The invention relates to a radio system for data transmission between transceiver stations (BS) moving along predefined paths and fixed transceiver stations (HS, ZS) disposed along these paths at predefined intervals and effective in both path directions, in which system the fixed transceiver stations (HS, ZS) of a path are connected via a cable (K) to a central transceiver station (CS). To prevent disturbing interference in the radio receiver in common-channel radio, it is provided that the frequencies of the individual fixed transceiver stations (HS, ZS) of each transmission section (UA) (modulation section) are offset slightly in relation to one another. In a broadband receiving component of the mobile transceiver stations (BS), the power of the received frequency-offset RF transmission signals of the fixed transceiver stations (HS, ZS) is added and occurring fade gaps are thus filled. <IMAGE>

Title: Sound insulating edge strip and method of manufacture
Inventor: QUITTMANN JUERGEN DIPL ING
IPC: E04F15/18
Filed: 1982-09-24
Abstract: Sound insulating edge strip for flooring structures composed of bare floor, footstep sound insulating layer and screed. The sound insulating edge strip consists of a sound insulating material and has, in cross-section, a sound insulating and separating portion, which is vertical when installed, and a holding flange capable of being angled off therefrom. When mounted, the holding flange grips under the screed or, alternatively, the footstep sound insulating layer. The holding flange consists of the sound insulating material of the sound insulating and separating portion and is formed from the latter by compression. The surface of the sound insulating and separating portion and that of the holding flange lie, on one side of the sound insulating edge strip, in the same plane. On the opposite side, they are joined to one another via a step. The holding flange can be turned away from the step by 90 DEG , without any incision. <IMAGE>

Title: Apparatus for centrifugation and simultaneous energy transfer from one centrifuge drum to a second one
Inventor: BALSTER HUGO DIPL PHYS DR
IPC: B04B9/10
Filed: 1982-11-08
Abstract: The invention relates to an apparatus for centrifugation and simultaneous energy transfer from a rotating centrifuge drum which has to be cyclically braked. A rotary movement is imparted to the two centrifuge drums, in that they are cyclically accelerated and decelerated in their respective directions of rotation by a power transfer which transfers the energy released on braking the first rotating centrifuge drum to accelerate the stationary second centrifuge drum. According to the invention, the brake required, after the energy transfer, for the following operation of a centrifuge drum at high rotational speed is replaced or supplemented, on the opposite centrifuge drum which runs at a lower speed, by a freewheel. The freewheel drives the centrifuge drum at a low rotational speed by short-circuiting the inner ring with the outer ring via an additional drive. The centrifuge drum which runs fast is driven via the differential gear. <IMAGE>

IPC: A01G25/09
Filed: 1983-03-03
Abstract: The present application is concerned with a sprinkling plant which is especially intended for air humidification and for this reason proposes suspended sprinkler pipes with one or more vanes. Pump energy converted into recoil is used as drive energy. Large land surfaces such as coastlines can be provided with such sprinklers, mounted on floats, so that so much air humidification can be produced that natural rain must ensue when the humidified air cools at night. The inventive concept also includes such suspended sprinklers which are seated as rotors on the sprinkler pipes.

Title: Device for relaying and providing electromagnetic signals
Inventor: SICHTERMANN HORST-GUENTER
IPC: G02B26/10
Filed: 1983-09-17
Abstract: For the representation of images in black and white or colour, image tube systems are known which are provided with electron beam generators and in which it is achieved by controlled deflection of electron beams that the latter impinge through perforated or slotted masks onto so-called phosphor triples arranged in rows and columns next to and above one another respectively and thereby produce the desired image. These image tube systems necessitate a large number of auxiliary devices which, for their part, require further electronic control and regulating devices. They are therefore not only technically complicated, but also expensive to operate. The invention disposes of these disadvantages by using, for the purpose of relaying and providing the electromagnetic signals, signal-conducting fibres which are combined, as the case may be, to form bundles, are situated with one end at the position provided for providing the signals, and are arranged with their other end at a distance from a rotatable mirror situated in the region of a radiation source and driven by a motor.
